Wikibooks:Files to be harvested

This page contains useful information about the Wikibooks project.
While this is not a listing of rules or policies, it contains information about an important Wikibooks process, custom etc. This page should be helpful to our users; please let us know if it is not.

This is a list of files that have been uploaded to serve as sources for text and images for the textbook project. Material from these can be used freely on this project.

For the time being at least, we can only use outside material that is already CC-BY-SA licensed or in the public domain. However, experience on Wikipedia has shown that authors that place their work under one free license tend to be very willing to grant us a CC-BY-SA license, if we ask nicely.
